CLIMBING DEVICE.

Specication of Letters Patent.

Patented Sept. 15, 19141` Application filed April 27, 1914. Serial N o.835,310.

To all 'whom 'it may concern the city and county of San Francisco andVState of California, have invented a new and useful Improvement inClimbing Devices, of which the following is a specification. Y

My invention relates to improved climbing devices wherein a tubularmember having o'set ends is provided with a climbing pulley adapted toengage a suspended rope run through the tube and wound around the saidclimbing pulley, which is operated by means of oscillating pedals, andis particu-A larly adapted for ascending or descending a suspended ropeas a lire escape, or, in ascending or descending from buildings andsimilar structures in course of erection, and the objects of myinvention are, first, to provide improved means for climbing a rope;second to provide improved means for preventing an involuntary descentof the climbing device; third, to provide improved oscillating pedalsoperating independently and adapted to rotate the wheel and climb therope; and fourth, to provide independent oscillating pedals which areadapted to operate suitable band brakes as well as the climbing wheel. Iaccomplish these several features by means of the device disclosed inthe drawings forming a part of the present specification wherein likecharacters of reference are used to designate similar parts throughoutthe said specification and drawings, and in which- Figure 1 is a brokenside elevation of a device disclosing the offset ends and the seatsecured thereto in a position substantially in alinement with thesuspended rope above the device; the manner in which the suspended ropeis run through the tube and around the pulley; the pawl and ratchet fornormally preventing a reverse rotation of the climbing pulley and themanner in which pawls pivotally secured to the under surface of theoscillating pedals are engaged to the ratchets which are in turn securedto the climbing pulley. Fig. 2 is a rear elevation of Fig. 1. Fig. 3 isan enlarged elevation of the climbing pulley disclosing the manner inwhich the suspended rope passes through the tube and around the climbingpulley, the manner in which the internal ratchet on the said climbingpulley is nor- `mally engaged by a pawl pivotally secured to the frame,the manner in which pivoted `pawls on the pedals engage the ratchetssecured to the climbing pulley and the manner in which band brakesengage the hub of ythe climbing pulley and the springs which -normallyraise each oscillating pedal inde-l pendently of the other pedal, andFig. 4, is a broken rear elevation partly in section disclosing thesleeve rotatably mounted upon the frame work of the device, the climbingpulley and the ratchets secured to the outer end of the4 sleeve andbeyond the frame work, and the oscillating pedals loosely mounted oneither end of a shaft rotatably mounted within the sleeve.

Referring to the drawings, the numeral 1 is used to designate avertically disposed tube having upper and lower offset ends 2 and 3,respectively. An open frame 1 is secured to the tube and arrangedintermediate of the ends thereof. Rotatably mounted within the frame 4is a sleeve 5 to which is yrigidly secured the climbing pulley 6provided with an internal ratchet 7 which is normally engaged by meansof a pawl 8 pivotally secured to the frame 4- and having connection, bymeans of a rod 9, with a handle 10 secured to the tube 1. rEhe climbingpulley 6 has a tread around which is wound a suspended rope or cable 12that passes through the tube 1 and around the pulley 11 set within thetube 1 for the purpose of reducing to a minimum the friction of the saidrope 12. Y

A ratchet 15 is secured to eachend of the sleeve 5. A shaft 16 isrotatably mounted within the sleeve 5 and has loosely mounted on eitherend thereof the oscillating pedals 17. lThe pedals 17 are normallyraised by means of suitable springs 18 loosely wound around the outerends of the shaft 1G, one end of each spring being arranged to engagethe frame 4, while the other end thereof engages the pedal 17, so thatthe tendency of the springs 18 will be to normally retain the pedals 17in an upper position against lugs 20 which are integral with the saidframe 4:.

Pawls 21 are pivotally secured to the under side of each pedal 17 andarranged to engage the teeth of the ratchet 15 secured to the outer endof the sleeve 5. Each pawl 21 is provided with an extension 22. Bandbrakes 24 each have one end secured to a pin of a frame l and afterpassing around the hubs of the climbing'A pulley 6 has the other endthereof secured'toa 'pin26' of the"` lever 27, which normally restsagainst pins 28 secured on either side of the frame 4. A

suitable saddle 30 is adjustably secured to4 l the tube l for thesupport of Vthe operator.

ll-he operation is as follows: lThe operator: is seated upon the saddle30 andby moving.

either Vpedal 17 downwardly alternately causes the 'pawls21 thereof toIlengage `the ratchets 15, which are secured to either end of the sleeve5to which is also securedthe climbing pulley- 6. vAsthe pedals 17 arelalternately moved downward, the, climbing pulley 6 is ,rotatedandclimbsthesuspendedy rope 12.

' tinued alternating.oscillation yof the pedals 17 .within a certain arcwill cause thepulley 6 `to `rotate-.and climb :the rope 1 2.

In order .to .lower the .device :either one .for bothof; the/pedals 17are. pressed f downward until the extension 22 ofthe-pawl21 engages theband brake lever ,2.7. As thereis considerable weight being supported bythe pawls 21, considerable. pressure ,is required during adownwardpressure. of either pedal 17 to;dislodge the 4p awl21 from .theratchetlA spring 35 is provided between each.

As the extension 22kis-pressed against the hand. brake27, thesaid lever causesthe bandbrake 241 to v.tightly engage .the hub of the climbing pulley .Gybefore.sufficient `reT sistance andV pressurecan .be obtained lto-release athe4pawl 2 1 ,from the ratchet .1;5 by

that the bandbralre 24: willljtightly vengage the hub of .the pulley 6beforethe vpawl 2.1 is disengaged from the ratchet ,15.

By means of the vhandle10 .andthe rod 9 the pawl g8 isfreleased from.the internal,
